TOOL AND MAGAZINE TABLE
(REF: 1505)
Tool and tool magazine table.
"Lc" - Cutting length
Length of the cutting edge.
"Ae" - Entry angle
This data is only shown on tools that are not for turning. Penetration angle for pocket milling.
Tool (length) offsets and offset wear.
The offsets are used to define the tool dimensions in each axis. The dimensions of the turning
tools are defined using these offsets; either these offsets or tool length and radius may be
used for the dimensions of the rest of the tools.
On tools that are not just for turning, e.g. endmills and drill bits, the offsets may also be used
to define the tool position when using a tool holder or an intermediate tool. In this case, the
tool dimensions are defined with the radius and the length.
The sign criterion for the offsets and their wear is established by machine parameter
TOOLOFSG.
In the tool table, it is possible to define whether the wear value being entered must be
incremental or absolute. In either case, deleting the wear value or setting it to 0 implies
resetting the amount of wear to 0. See "Select the type of wear values to enter, incremental
or absolute." on page 257.
Using incremental wear, the value entered by the user will be added (or subtracted if it is
negative) to the absolute value of the wear. After pressing [ENTER] to accept the new value,
the wear field will show the resulting absolute value.
TOOLOFSG Meaning.
Negative. Tool calibration returns a negative offset. The offset wear must be entered with
a positive value.
Positive. Tool calibration returns a positive offset. The offset wear must be entered with
a negative value.
